Paramount PAR17504 Hex Key 5/64 Inch Ball End

Product Description

The PARAMOUNT PAR17504 is a 5/64 inch ball end hex key with a long arm design, built for fastener access in confined or angled spaces. Machined from steel, this L-key delivers the torque needed for socket head cap screws and set screws common in HVAC equipment, pool hardware, and mechanical assemblies. The ball end allows engagement at off-axis angles, reducing the need to reposition the tool when clearance is tight. The long arm provides increased leverage on the drive end and a shorter quick-turn arm on the opposite side. Overall length is 3-3/16 inches.

This hex key is suited for service technicians and installers working on equipment fasteners in residential and light commercial settings. Common applications include tightening or loosening set screws on motor shafts, fan hubs, and valve stems, as well as adjusting fasteners inside panel enclosures where straight access is limited. It is a standard hand tool carried by HVAC technicians, plumbers, pool equipment service pros, and general mechanical contractors.

Key Features

• Ball end tip allows fastener engagement at angles up to approximately 25 degrees off-axis
• Long arm geometry increases torque on the drive end
• 5/64 inch hex size fits corresponding socket head cap screws and set screws
• Steel construction for durability under repeated torque loading
• Compact 3-3/16 inch overall length suits tight service envelopes

Compatibility

Designed as a standard 5/64 inch L-style hex key compatible with any socket head cap screw or set screw requiring a 5/64 inch hex drive.

Installation Notes

No power isolation is required for hand tool use, but always de-energize and lock out equipment before reaching into enclosures or working near live components. Use the short arm for initial fastener engagement and the long arm for higher-torque final tightening. Do not apply excessive side load to the ball end tip, as it is not rated for the same torque as a flat hex engagement. Inspect the tip for rounding before use and replace if worn.
